STOPPING MECHANISM FOR WIRE-WINDING MACHINES.

Specification'of Letters Patent.

Patented Dec. 21, 1920.

Application filed December 16, 1919. Serial No. 345,178.

T all whom it may concern Be 1t known that I, Josnrrr Pnnnnr, a citizen of the United States, and resident of Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Stopping Mechanism for Wire-l/Vinding Machines, of which the following is a specification.

My invention relates to stopping mechanism, the invention being more particularly related to an improved mechanism having an automatic character for use in connection with wire winding machines, wire drawing machines and the like.

A main object of the invention is the revision of a mechanism of the kind specified, adapted automatically to unclutch or throw out of operative engagement the take-up mechanism of wire winding or drawing machines, whenever the wire strand becomes either tangled, knotted, or broken.

Another object of the invention is the provision of a mechanism of this character embodying cooperating means for automatically locking certain of the parts in the relative positions they occupy when the unclutching action is effected.

A further object is the provision of mechanism, embodying the foregoing features, which is of simple, compact and inexpensive construction, and which includes means by which it maybe actuated manually as well as automatically.

Other objects and advantages will appear a in the following specification and the novel features of the mechanism will be particularly pointed out in the appended claims.

My invention is illustrated in the accom-- panying drawings forming part of this application in which I Figure 1 is a view in perspective of the preferred form of easing, designed to hold my improved mechanism as well as the wire take-up mechanism. I

Fig. 2 is a vertical cross section, taken centrally through the casing, and more specifically in the direction of line 22 of F ig. 3.

Fig. 3 is a vertical cross section, taken on 1 the line 3-3 of Fig. 2.

Fig. tis a perspective view of the wire guide block with its pulley.

Fig. 5 is a cross section, looking in the direction of the line 5-5 of Fig. 2.

Fig. 6 is a detail view of the gage or die block; while Fig. 7 shows across section on the line 7-7 thereof.

Fig. 8 is a orizontal cross section, showing the parts as they appear when looking in the direction of the line 8--8 of Fig. 2.

.Figs. 9 to 14 inclusive are various views of the clutch, shown in successive phases of operation. Of these views, Figs. 9, 11, 12 and 14 are cross sections, Fig. 11 being taken on the line 1111 of Fig. 10, and Fig. 14 on the line lee-1a of Fig. 13. Fig. is a longitudinal section, and Fig. 13 a side elevation.

In carrying out my invention, I preferably make use of a box-like casing consisting of parallel front and back plates 15 16, parallel side plates 17 18, and parallel bottom and top plates 19 20. Through the center of the top 20 is cut a circular aperture 21, in which works a clutch element 22, fast on the vertical shaft 23 having bearing in a block 2 1, bolted to the underneath side of the said top, and also in a central bracket 25, rising from the bottom 19. Formed to have clutching engagement with the element 22 is the axially projecting hub portion 26 of the flanged take-up or pulley 27, loosely mounted upon the shaft 23 above the top plate 29. Provision for effecting the clutching engagement may be made for instance by providingthe element 22 with a rack tooth 28, which is adapted to enter a corresponding recess cut in the hub portion. Unclutching action is effected by elevating the take-up until the hub portion is clear of the rack tooth; and means through which to accomplish this both automatically and manually will be hereinafter described.

Journaled in the central bracket 25, as well as in other brackets 29 alined therewith is a horizontal drivingshaft 30, which projects through an opening 31 provided in the casing side 18, so that the means (not shown) for rotating the shaft may be applied exteriorly of the casing. Movement is imparted to the vertical shaft 23 from the shaft by means of the engaged bevel gears 32 and 33.

As best illustrated in Figs. 1 and 2, there is bolted to the front and top plates 15 and 20, an angular plate 34- constituting the rear plate for a casing including parallel side plates 35 86, a downwardly inclined bottom 37, a front plate 37, and confronting top strips 38 upon and between which is arranged a plate 39 having movement toward and away from the take-up. With this slide plate 39 is cast an operating handle 40, a front upstanding flange '41, and a rear channel-shaped holder 42 for operatively receiving a gage'block 43,provided with eyes or reducing dies as 44 through which is. drawn the wire to be wound upon the takeup. The gage block 43 is shiftable either to the right or to the left, and the eyes or dies therein differ in size so as to make provision for handling-wires of different gages.

-Depending centrally from the slide 39 is a vane 45, against the inner side of which abuts the short arm of a bell crank lever 46, tiltable on a fixed pivot 47, carried between the lugs'48, outwardly projecting from the plate 34. The long arm of the bell crank lever projects through suitable openings into the main casing, where, by means of slot and pin'structures 49and50, it has operative connection with a bar 51, which extends downward and terminates in an angle 52, hifurcatedas shown to operatively receive the end of an arm 52, projecting at right-angles from a shipping lever shaft 54, to be presently described.

Acting 011 the short arm ofthe bell crank lever so as to maintain the slide 39 normally in its outermost position is a push spring 55. Movable on the fixed pivot 47 alongside the bell crank lever is a lever 56, which pro-' jects through a suitable opening provided 7 inthe front plate 37and terminates in a reduced portion 57. With this lever is also formed a rearwardly curved arm 58 having a laterally bent'lug 59 (Fig. 5) adapted to engage the short arm of the bell crank lever. Engaged upon the reduced end 57 and adj'ustable thereon by means of a set screw 60 is an elongated block 61, provided with a grooved wire pulley 62, one side of this block having an opening 63 to permit of the lengthwiseinsertion of a strand of wire, said openingbeing normally closed by a flexed" spring 64, pinned to the block at 65. Asshown in Fig.2, a wire strand as 66, to

be coiled on thetake-up, isengaged under the pulley 62' of block 61, and then over an idle pulley 67, carried by bracket 68, which projects upwardly at anangle from the front plate 37" and at such elevation that the 1 strand is held in line with the selected gage .block44 through which it is to pass. The front slide flange 41has a notch 69, and

- the channel-shaped piece 42 has central openings through. which the strand passes. On opposite sides of the path of the strand, posts e971 rise from'the angle plate 34 to serve as guides for the strand. Should the wire strandbecome kinked or knotted so that it cannot be drawn through the block 61 under the pulley 62, the lever 56 will be elevated in an obviousmanner tilting the bell c'rank lever 46 inwardly upon {its axis and turning the shaft 54 a distance. Should the wire strand stick in the gage block or become kinked or knotted in front of the same, an equivalent result is obtained; the bell crank lever in this case,'however, being tilted by the vane 45 as the slide is drawn toward the take-up under the pull of the wire strand.

The shaft 54, which is turned a distance through the movement toward the take-up of either lever 57 or slide 39 as described, is journaled in the lateral lugs 72 and 73 of the floor bracket 74. Fast with the shaft 54 is a shipping mounted on the driving shaft 30, said clutch part being slotted at 78 so as to have limited axial movement on a pin 7 9 by which it is held to said shaft. The face of this clutch part is formed with an outwardly beveled peripheral lug 80 with an axially directed shoulder 81. The bottom bracket 74' has an upstanding part 82, which terminates spacedly from the shaft 30- so as to form a guide arm against which bears the loose clutch part 83, held in position on .the driving shaft by a collar 84 pinned thereto at 84. Said clutch part 83 carries apin 85 close to the driving shaft so asto clear the guide arm but in position to be engaged by the lug shoulder 81 when the clutch part 77 is thrust over bythe shipping lever under the turning of the shaft 54. When, through the engagement of theshoulder 81 with the pin 85, the clutch part has been turned the desired distance as shown in Fig. 14, the guide plate 82 engages the lug 80 and thrusts the part 77 over,disengaging the shoulder from the pin. I

' Pivotally connected at 86 with the clutch part 83 is a link 87, whose'upper end is connected at 88 with a lifting lever 89, fulcrumed at 90'to a bracket 91, secured to the rear plate 16. The forward end of this lifting lever is reduced at 92 to work in an angled slot 93 cut through the front plate 15. v V j Depending from the block 24 are the hangers 94, carrying a rock shaft 95, to the outer ends of which art secured the rocker bars 96, whose inner ends extend-into the plane of the vertical shaft 23one on each side thereof. Rising from the inner ends of these bars are uprights 97 carrying rollers 98 engageable with the take-up pulley. One of the rocker bars 96 is connected at its forward end with the lifting lever 89 by a link 99, so that when the lifting lever 89 is drawn down by the turning of the clutch part 83, the take-up pulley will be raisedfrom the rack tooth of the clutch element 22. Ohviously, the movement of the clutch part 83 is limited by the engagement of the reduced lever end 92 with the bottom wall of the slot 93; and immediately said bottom wall is lever 75, which works inreached, a spring 100, connecting the lifting lever with the side plate 1?, draws the re duced end 92 into the horizontal end of the slot 93, whereupon the parts are securely locked with the take-up pulley in elevated position.

From the foregoing description, taken in connection with the accompanying drawings it will be understood that each time the bell crank lever 46 is tilted as hereinbefore described, whether by the slide 39 or by the lever 56, the take-up pulley 27 will be automatically elevated from its clutch to ride loosely upon its shaft. It will also be understood that the slide 39 may be actuated at will by means of the handle 40; and further that the lifting lever 89 is always free to be operated independently of its automatic operation by the slide 39 or lever 56.
